remoteproc: mtk_scp: Reorder scp_probe() sequence
Cleanup the scp_probe() function by reordering some calls in this
function, useful to reduce the usage of goto(s), and preparing
for one more usage of dev_err_probe().
In particular, we can get the clocks before mapping the memory region,
and move the mutexes initialization right before registering the ipi
handler (which is the first mutex user in this driver).
